(* means a trouble report has been issued or appended to)
1st half observing specialist: Camron Hastings
    I did not open the telescope tonight due to high winds, rising
humidity and general unstable atmospheric conditions.  We did notice
that when the wind shifted all observable phenomenon told us of very
high wind gusts, although the MET tower wind gauge read only 29 mph
gusts.  We took a reading with the hand held anemometer and found gusts
near 40 mph, which seem closer to reality.
    The first half was not all lost.  Jeff Morgon found odds and ends
to tie up while we were closed and Russ Owen was able to test the new
TCC code while we were closed.  So far it is looking very good for both
projects!
2nd half observing specialist: Karen Gloria
The telescope remained closed for the second half of the night.  The
sky is overcast and the radar map indicates precipitation marching
northward from Mexico.
